8 Claims.

My invention pertains to writing brushes or daubers and more particularly to an automatic flowing fountain brush or dauber in which the writing fluid may be stored for automatically and continuously wetting the dauber. v

It is an object of my invention to provide an automatic flow writing brush or dauber of the fountain type which is simple to construct and assemble, which is convenient to fill and refill,

and to hold and write in various positions.

It is also an object of my invention to provide a simplified fountain brush or dauber comprising a tubular writing fluid reservoir having an aperture in one end suitable for receiving and retaining a fibrous dauber therein, and open atthe opposite end for receiving writing fluid retained therein by a suitable closure member.

It is a further object of my invention to provide an automatic fountain brush or dauber compris- 9) ing a writing fluid reservoir open at one end for receiving and discharging writing fluid and comprising means for receiving and securing a tubular sleeve thereon having an aperture inits remotely extended portion for securing a fibrous dauber therein, and having an annular baifie flange adjacentthe fluid reservoir for storing a quantity of fluid adjacent the dauber, whereby. the brush is constantly maintained in a dampened condition, ready to write, even when a small quantity of fluid remains in the reservoir, since it is apparent that the logical resting position of the reservoir is a horizontal one and that some of the fluid is always trapped adjacent the dauber when the brush is held in a position for writing.

Other objects of my invention will become evident from the following detailed description taken in conjunction with the accompanying drawings, where like reference characters refer to similar parts throughout, and in which:

Fig. 1 is a side elevational view of an automatic fountain writing brush or dauber constructed in accordance with my invention;

Fig. 2 is a longitudinal sectional view therethrough on section line 2--2 of Fig. 1;

Fig. 3 is an enlarged sectional view on line 3-3 of Fig. 2 to illustrate the construction of the dauber and its retaining means; v

Fig. 4 is a side elevational view illustrating another embodiment of my automatic fountain h; r

Fig. 5 is a side elevational view of a fountain brush cap which is adapted to he slipped over the end of the dauber when the brush is not in use;

a and Fig. 6 is a longitudinal sectional view through section lines 5--6 of Fig. 4.

Referring more particularly to Figs. 1, 2 and 3 of the drawings, my fountain brush or dauber comprises an elongated tubular reservoir member 5 l of substantially cylindrical conformation which is open at opposite ends. The reservoir member may be of any size and shape to provide a convenient handle for using my fountain brush and it may be made of anysuitable material, but is 10 preferably made of glass for the convenience of the user in observing the quantity of ink or other colored writing fluid therein. Adjacent one end of the reservoir tube l, I provide an inwardly depressed circumferential groove 3 which is spaced II a short distance from the end of the tube.

For continuously conducting a suitable quantity of the writing fluid from the tube for writing, making show cards, daubing, retouching, and the like, I provide a dauber member 5 which is of 90 circular cross-section having a suitable diameter for loosely fitting into the end of the reservoir tube adjacent the circumferential groove 3. The dauber 5 is of a suitable fibrous material, such as felt for example, although any other fibrous mate- 25 rial may be utilized of suitable texture to provide the desired quantity of writing fluid for the purpose desired. The fibrous dauber is of substantially cylindrical conformation, save that the inner end may be made of lesser diameter as shown in 30 Fig. 3, and where that is not done, the retaining member, hereafter to be described, squeezes opposite sides as hereafter described.

Portions of the dauber are cut away from the peripheral edge of the outwardly projecting end 35 at opposite sides thereof, thus providing a tapered wedge-shaped point i, as shown in Figs. 1 and 2.

The wedge-shaped point 1 of the dauber is a convenient conformation for writing. making show cards and the like, because of the convenience to with which it may be utilized for making strclres or lines of varying widths.

For securing the dauber .5 in the end of.the reservoir tube I, I provide a resilient retainer H of substantially inverted U conformation, the 45 ends of the retainer comprising inturned claws it which project into the dauber, forming apertures 9 in opposite sides of the dauber. The side legs of the retainer ll'are provided with inwardly curved seatportions 15 at an intermediate portion thereof for fitting over the indented groove 3 of the tube which seats therein when the dauber and its retainer are positioned into the end of the tube. This retainer gives to the dauber a substantially floating, pivotal mounting, allowing free flow or fluid around a portion of the dauber at all times.

To make a snug hermetical seal around the end of the tube and between the dauber and the side walls of the tube, I provide a rubber sleeve ll of such a size that it can be pulled and stretched snugly over the end of the tube and the dauber, gripping the indented groove 3 as well as the dauber ii.

For expediting the operation of the fibrous dauber 5 in conducting the writing fluid to the point thereof, the'inner portion of the dauber, designated at ll, may be made with a smaller diameter less than the inner diameter of the inner walls of the reservoir tube i, as shown more clearly in Fig. 3, or the side portions of the retainer ll may be relied upon to squeeze the opposite sides of the inner portion of the dauber to permit fluid to flow down said sides and into the apertures 9.

The opening at the opposite end of the tubular reservoir member is provided merely for convenience in filling and refilling and is closed by a stopper i9 which may be made of cork, rubber or any suitable material for retaining the writing fluid. My fountain brush is readily assembled by applying the retainer H to the felt dauber 5 by springing the claws ii of the retainer into the ends of the apertures i3 in the dauber. The dauber and the retainer are then pushed into the end of the reservoir tube i until the seat portions ii of the retainer snap securely over the inwardly directed groove or ridge 3 in the side walls of the reservoir tube. The

resilient rubber sleeve i1 is then stretched and pulled tightly over the lower end of the tube where it provides a hermetical seal around the tube and dauber. By removing the stopper l9 from the other end of the tube, a suitable writing or retouching fluid, paint' or other colored fluid is poured into the reservoir member where it is retained by the stopper. This filling operation could otherwise be accomplished in a bottle form of tube by merely filling the bottle prior to inserting the dauber, etc.

The fountain brush is then prepared for use and it is utilized very convenientlyfor writing, making show cards, daubing, retouching and the like. The fibrous dauber 5 is selected of suitable texture for the writing fluid and the purpose for which it is used.

Referring more particularly to Figs. 4 through 6, in accordance with another embodiment of my fountain writing brush, I provide a writing fluid reservoir which comprises substantially an elongated bottle 2i of a small diameter suitable to constitute a convenient handle for using the appliance. In this embodiment of my invention, the fluid applying dauber 5 and its resilient retainer Ii are firmly secured in the outer end of a tubular sleeve 23, which may be of metal or other suitable material, and is provided with an inwardly pressed groove 25 which is adapted to engage and secure the seat portions l5 of the retainer. In the opposite end of the dauber supporting sleeve 23, I insert a screw-threaded cap 21 which is firmly secured in the sleeve in any suitable manner as by pressing it therein under high pressure. As will be readily understood, further attachment may be provided therebetween as by soldering, or in any other suitable manner. The neck of the reservoir bottle 2i is provided with an external thread 26 of suitable conformation for threadably receiving the cap 21 whereby the dauber extending end of the retainer Ii.

supporting sleeve 23 and dauber 5 may be firmly secured thereon.

In order to freely pass the writing fluid from the reservoir 2i into the dauber sleeve 23, a portion of the closed end of the cap 21 is pressed out to provide an aperture 28 of substantially smaller diameter than the sleeve 23 whereby an annular flange 29 is provided adjacent the mouth of the reservoir bottle I. As shown, the aperture 29 may also serve to receive the inwardly The flange 29 also serves as a baille for the storing at all times of a larger quantity of writing fluid in contact with the dauber than would otherwise be the case, especially when the reservoir is nearly empty. It should be realized that it is of great importance to have the brush kept moist at all times so that one does not have to wait till the dauber becomes saturated before being able to write with it.

In operation, the reservoir 2i is filled with writing fluid and the sleeve 23 carrying the dauber 5 is screwed thereon. My automatic writing brush is then prepared for use and may be conveniently used for writing, daubing, marking, retouching and the like. When the supply of fluid in the reservoir 2i is substantially exhausted so that only a small quantity remains, the annular flange 29 in the dauber sleeve 23 comprises baille means for retaining a quantity of the fluid adjacent the dauber 5 through which it is drawn by capillary attraction to the point 1. By this arrangement my automatic writing brush may be successfully utilized for writing with the brush in a substantially horizontal position until practically all the writing fluid I is used up from the reservoir chamber 2|.

When my fountain brush is not in use, the dauber is preferably protected by placing thereon a vented cap such as that shown in Fig. 5. The cap is of a suitable size to fit down snugly over the dauber 5 and it prevents excessive evaporation therefrom and protects the dauber from receiving a deposit of dust whereby the fountain brush is ready for prompt operation.

It will be seen that I have provided an automatic fountain brush which is simple to construct and assemble and which is convenient to fill and use in various positions.

Although I have shown and described certain specific embodiments of my invention, I am fully aware that many modifications thereof are possible, my invention therefore is not to be restricted, except insofar as is necessitated by the prior art and the scope of the appended claims.
